Error using matlab.internal.imagesci.netcdflib
The NetCDF library encountered an error during execution of 'open' function - 'Unknown file format (NC_ENOTNC)'.
Error in netcdf.open (line 67)
[varargout{:}] = matlab.internal.imagesci.netcdflib ( 'open', filename, varargin{1} );

@Lilya: It seems like your file is empty.

@Lilya, did you create this file or are sure it originated from a mapping system using Golden Software's grid format? Could be another unrelated application like Photoshop. Use a binary editor to look at the first sector and see if there are readable identifications. Even if it is in Golden Software's grid format that apperently has ASCII and binary forms that may not be compatible with the platform you are using or either of these two readers you have tried.
